Hi pinside members,
I have a Gottlieb Solar City 1977 with a weird problem. It is set to play 3 ball game. When the first ball drains I get double bonus. When the second ball drains I get double bonus too. The double bonus light is off for the first two balls. But when the third ball drains I get single bonus even the double bonus light is on. I did not find anything on that forum about that kind of problem. Someone has an any ideas? Thanks for your help!
